Been trying to figure out how to get passed the configuration and ICMP scan. I have put port 41 into the routers virtual server, port forwarding and still getting IP is not ICMP pingable. "Please make sure ICMP is not blocked. If you are blocking ICMP, please allow 66.220.2.74 through your firewall." message.
Should I configure HE and a PC directly to the ISP modem first then put the DIR back in the loop?

I'm running Windows 7x64
DIR-825 v2.05 FW.
Cableone Internet (50Mb/2Mb)

Please let me know if there is already step by step instructions for this router. Thank you.
